ABSTRACT

In general, the present disclosure includes a system, method and architecture for use in analyzing content of a social network data to identify a financial market trend, e.g., a trend associated with a financial market instrument.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of and claims priority from U.S. patent application Ser. No. 13/104,769, filed May 10, 2011, entitled METHOD AND APPARATUS OF ANALYZING SOCIAL NETWORK DATA TO IDENTIFY A FINANCIAL MARKET, which issued as U.S. Pat. No. 8,301,545 on Oct. 30, 2012.

FIELD OF THE DISCLOSURE

The present application relates to analyzing social data, such as without limitation tweets, comment streams, user comments, etc., to identify a financial market trend, and more particularly to analyzing social data to identify a social data trend for purposes of analyzing a financial market trend, a trend associated with a trade, investment, and/or exchange, such as may occur in connection with a stock, bond, commodity, currency, derivative, index or other instrument, e.g., financial market instrument, of value.

BACKGROUND

Financial investors can use trends, e.g., trading trends, to identify investment opportunities, or lack thereof. For example, an investor might elect to invest, e.g., in a stock, mutual fund, bond, index, etc., if the investor believes that the item's price is about to, or has begun, trending upward; and conversely, the investor might elect to sell the item if the item is about to, or has begun, trending downward. Some conventional approaches use current and historic objective information, e.g., volume of trades, price, price volatility, etc., to make predictions.

DETAILED DESCRIPTION

In general, the present disclosure includes a system, method and architecture, and includes a method and apparatus of analyzing social network data to identify a financial market trend, e.g., a trend associated with a financial market instrument. By way of one non-limiting example, a trend identified in accordance with one or more embodiments disclosed herein might be used to decide whether to trade a financial market instrument.

Certain embodiments of the present disclosure will now be discussed with reference to the aforementioned figures, wherein like reference numerals refer to like components.

In accordance with one or more embodiments, the social network data comprises messages, which are also referred to herein as comments, such as without limitation messages, posted to a social networking service such as Twitter®, Facebook®, Myspace®, a blogging and/or microblogging service, and may include messages that are published or otherwise made public from an instant messaging service, text messaging service, electronic mail service, etc. The messages may also include messages generated by a service that monitors financial market transactions, e.g., the service might generate a message when an officer of a company sells, or buys, some shares in the company. By way of another non-limiting example, the messages might include messages posted by a service that tracks trades made by users registered with a service, a social networking service, or trades identified by the service that are made by other entities; the social networking service posting a message containing information about each trade including a reference, e.g., a ticker symbol, for the financial institution involved in the trade. One example of such a service is provided by Covestor LLC.

Content of each of a plurality of messages occurring during, within, or in a time window, or time span, is analyzed to determine whether or not the message contains a reference to a financial market instrument, which reference is also referred to herein as a financial market instrument reference, financial market reference, instrument reference, or reference. For sake of simplicity, the reference primarily used herein is a ticker symbol, which is just one example of a financial market reference, and the financial market instrument primarily used herein is stock, which is just one example of a financial market instrument. It should be apparent that embodiments described herein apply equally to any type of financial market instrument reference and/or financial market instrument.

Using stocks and ticker symbols as an example and without limitation, for each of a plurality of stocks' ticker symbols, messages occurring during a selected window, or span, of time are analyzed to identify a number of the messages occurring during the time span and containing a stock's ticker symbol. Each message has associated temporal data, e.g., a date and time. The temporal data can be indicative of a time when the associated message is generated, received, etc., for example. For each ticker symbol identifying a stock, a time span average is determined using the number of messages occurring during the time span and containing the ticker symbol and a number of time intervals into which the time span is divided. One of the time intervals is selected, e.g., the most recent time interval in the time span. By way of one non-limiting example, the time span might be one week, e.g., the prior week including the current day, and the selected time interval might be the last hour of the current day in the time span. It should be apparent that any time span, number of time intervals and selected time interval can be configurable.

For the selected time interval, e.g., the most recent time interval in the time span, the messages occurring during the selected time interval are analyzed to identify the number of messages occurring during the selected time interval and containing a stock's ticker symbol. For each stock's ticker symbol identified in the messages, a percentage change is determined for the selected time interval and the stock's ticker symbol as a ratio of the number of the messages occurring during the selected time interval and containing the stock's ticker symbol over the time span average.

A number, n, of the stocks can be selected for presentation to users based on a comparison of the percentage change values determined for the stocks in accordance with one or more embodiments. By way of a non-limiting example, the percentage change is a percentage increase, which reflects an uptick, or upward trend, in attention to the stock as determined by analyzing the messages, including social networking service messages. In accordance with one or more embodiments, the financial market instrument reference, e.g., ticker symbol, associated with each of the n selected financial market instruments is saved, and can be selected for presentation to users. In a case that the percentage change is a percentage increase, the financial market reference for each of the n financial market instruments having the greatest percentage increase relative to the percentage increases associated with the other financial market instruments are presented to the user. By way of a non-limiting example, the ticker symbols associated with the top n stocks, e.g., the n stocks with the greatest percentages increase relative to the other stocks that were considered, are presented. It should be apparent that embodiments of the present disclosure are not limited to a percentage increase; and that a percentage decrease or no change can be used as selection criteria.

In accordance with at least one embodiment, selection of a financial market instrument reference is based on a percentage change, e.g., percentage change in volume or acceleration, rather than message volume. To illustrate, assume that a first financial market instrument, on average, is referenced in 100 messages per hour over the past week and 110 messages in the last hour, and a second financial market instrument, on average, is referenced in 5 messages per hour over the past week and 50 messages in the last hour. Using either the average volume, or the raw message count for the last hour, as the selection criteria, the first financial market instrument is selected over the second. A percentage increase as determined using embodiments of the present invention show a much greater increase in volume for the second financial market instrument, i.e., 900% increase in volume in the last hour over the average volume per hour, relative to the 10% percent increase in volume for the first financial market instrument. By comparison, the second financial market instrument's percentage increase indicates that the second financial market instrument signifies a greater acceleration and is more trending in the last hour than the first, even though the volume of messages for the second financial market instrument is less than the first. In accordance with one or more embodiments, a trend, or change such as is determined by a percentage change metric, can be identified for a financial market instrument relative to the instrument's own message volume, and the instrument's trend is compared with trends of other instruments to identify a set of instruments for presentation.

FIG. 1 provides an example of a graphical user interface (GUI) used in presenting a set of stock ticker symbols in accordance with one or more embodiments of the present disclosure. GUI 102 includes a listing 104 identifying ten of the financial market instrument references, ticker symbols determined in accordance with at least one embodiment of the present disclosure. In the example shown in FIG. 1, the listing includes the financial market entities, e.g., companies, associated with the ticker symbols. It should be apparent that the listing can contain fewer or more references than that shown in listing 104. In the example shown in FIG. 1, listing 104 is a portion 110 of GUI 102. GUI 102 includes at least one other portion, portion 112, which includes a listing 106 of messages, e.g., sorted based on time. While only four messages are shown in the example, it should be apparent that GUI 102 can include additional messages, and that the user can use the scrolling capabilities of GUI 102 to view additional messages. While not shown in FIG. 1, GUI 102 can include an option selectable by the user to obtain additional messages and/or trending tickers for presentation in GUI 102.

In the example of FIG. 1, the messages shown in listing 106 includes messages containing a specific ticker symbol, YHOO. It should be apparent that listing 106 could include messages containing one or more other ticker symbols. By way of one non-limiting example, field 108 can be used by a user to display messages containing one or more ticker symbols input using field 108. In response, listing 106 can be updated to include messages, each of which contains at least one of the one or more ticker symbols specified by the user. To illustrate further and without limitation, each ticker symbol in listing 104 might be selectable by the user to view messages, as displayed in listing 106, which contain the ticker symbol selected from listing 104. Alternatively, a ticker symbol in listing 104 might be used to display additional information about the associated financial market entity, e.g., in a portion of the same or a different web page. In the example, each ticker symbol contained in a message is a hyperlink, which might be used to display messages containing the ticker symbol in listing 106 and/or to view additional information about the financial market entity, e.g., company, associated with the ticker symbol. GUI 102 can include additional links, or hyperlinks, e.g., a hyperlink to content and/or a web page. A hyperlink can be included in a message contained in listing 106, and/or in an entry contained in listing 104, for example.

In the example shown in FIG. 1, each message includes a hyperlink at the beginning of the message. By way of a non-limiting example, in a social networking message, the hyperlink might be used by the user viewing GUI 102 to navigate to a web page served by one of the social networking service providers, e.g., a social networking service provider that provided the message; the web page might contain information associated with the user that posted the message with the service provider, and might further allow the user of GUI 102 to connect with the message originating user, e.g., view information about the message originating user and/or follow the message originating user. By way of another non-limiting example, in a case that the message is generated by the service providing the message, the hyperlink might be used to display a web page containing information about the service, e.g., a financial news service, which provided the message.

Each message shown in the example includes temporal information, e.g., information indicating a time and in some cases a date, e.g., in a case that the message occurred before the current day/date. In the example, the temporal information is shown below the message. Additionally, in the example, the source, or service provider, of the message is indicated, e.g., the icon shown to the left of the temporal information.

In accordance with one or more embodiments, listing 104 is updated on a period basis, e.g., every ten minutes, every hour, etc. The time period is configurable, and may be based on the volume of messages being received, volatility of one or more financial markets, etc.

FIG. 2 illustrates components of an exemplary system in accordance with one or more embodiments of the present disclosure. In accordance with one or more such embodiments, one or more data providers 202, e.g., social networking service, news service, etc., provide messages containing financial market instrument references to receiver 204. In accordance with one or more embodiments, each message that is received has associated temporal information, e.g., a time stamp, which can be provided by the data provider 202 or generated by receiver 204. The time stamp might indicate a time that the message is posted by a user or server, and/or the time that the message is received by receiver 204. As discussed above, each message can include, or have associated therewith, information to identify the service provider 202, the user generating the message, and one or more financial market instrument references.

The received data is stored in data store 206 and is used by analyzer 208 to identify a set of financial market instrument references. The set of references identified by analyzer 208 can be stored in data store 206, and retrieved by server 210 for inclusion in a web page, e.g., GUI 102, that is served to user device 212 for presentation to a user of device 212.

Each of data provider 202, receiver 204, analyzer 208, server 210 and user device 212 comprises at least one computing device. As is described in more detail below, a computing device can comprise one or more processing units. Data store 206 includes memory to store data and may comprise a computing device. Data store 206 can comprise more than one data store, and may be integrated into one or more of the other components shown in FIG. 2. Additionally and while the components are shown separately, it should be apparent that one or more of the components shown in FIG. 2 can be combined to form one component.

FIG. 3 provides an example of pseudo code for use in accordance with one or more embodiments of the present disclosure. The pseudo code provided in FIG. 3 can be used by analyzer 208 to generate the set of financial market instrument references, for example.

In the example shown in FIG. 3, “[ ]” brackets are used to indicate a configurable value, and “< >” brackets are indicative of a value in a loop. A loop begins at step 1 and includes steps 2 through 5, which are repeated for each financial market instrument reference found in messages provided by data providers 202. In the example, a financial market instrument reference is referred to as a “ticker”. The loop is performed for each ticker received in the last hour. The time span of the last hour is configurable.

Step 2, which includes steps 2 a-2 d, is optional and can be used to filter messages. Step 2 a, for example, can be used to filter out a ticker symbol if the number of messages, or comments, containing the ticker symbol is less than the configurable threshold number of messages, e.g., three messages. Another optional filter is shown in step 2 b, which filters out messages that contain a ticker symbol associated with an instrument, e.g., a stock, which has an average trading volume below a configurable threshold, e.g., one million in the pseudo code example. Step 2 c optionally filters out the messages received from a data provider 202 if the number of messages from the data provider 202 in a configurable time interval, e.g., last hour, exceeds a configurable threshold number, e.g., 80%, of the comments received in the configurable time span. Step 2 d optionally filters out messages received from a user if the number of messages from the user in a configurable time interval, e.g., last hour, exceeds a configurable threshold number, e.g., 80%, of the comments received in the configurable time span.

At step 3, an average number of messages received is determined. By way of one non-limiting example, the average is determined to be the number of messages received in a configurable time span, e.g., one week, divided by the number of time intervals in the time span, e.g., the time interval in the pseudo code example is configurable and is set to one hour. Step 3 a provides one example in which the average for the YHOO ticker symbol is determined to be 10, e.g., 1680 messages÷(24*7 hours in one week)=10.

At step 4, a percentage change, e.g., a percentage increase, is determined using the average determined in step 3 and a number of the messages occurring during the last interval, e.g., last hour, of the time span, e.g., one week. In the example shown in step 4 a, the percent increase is determined by dividing the result of subtracting the time span average determined in step 3 from the number of messages occurring during the last hour by the time span average, and multiplying that result by 100. At step 5, the percent increase is stored together with the ticker symbol.

In the example pseudo code in FIG. 3, the loop is executed hourly for the messages that occur, e.g., are received, during the last hour. Step 5 can also save the count of messages occurring during the last hour and containing a given ticker symbol, and the number, or count, of messages occurring during the last week and containing the ticker symbol can be determined by aggregating the count determined for the last hour and the counts determined for each hour before that, since each of the determined is stored in step 5.

With reference to step 6 of the sample pseudo code, the ticker symbols are sorted in descending order by their respective percentage increases. A number, e.g., ten, of the top, e.g., first, ticker symbols in the sorted ticker symbols are selected for presentation at step 7. Each of the ticker symbols selected in step 7 has a percentage increase that is greater than the percentage increase of all of the unselected ticker symbols. At step 8, in a case that the selected number of ticker symbols does not meet the desired number of ticker symbols, ticker symbols selected in a previous execution of the pseudo code, e.g., the hour just prior to the last hour, can be selected for inclusion in the set of ticker symbols, e.g., below the ticker symbols selected in the current execution of the pseudo code, and the set of ticker symbols as selected in step 7, and possibly in step 8 as well, can be stored, e.g., in data store 206.

FIG. 4, which comprises FIGS. 4A-4C, provides an example process flow in accordance with one or more embodiments. With reference to FIG. 4A, the process flow, which can be executed by analyzer 208, analyzes messages received from one or more data providers 202 to count the messages that include a financial market instrument reference, such as a ticker symbol. At step 402, a determination is made whether or not to process incoming messages, e.g., messages received from data providers 202. By way of a non-limiting example, the process flow shown in FIG. 4A can be executed periodically, e.g., every ten minutes, every hour, etc., and the period can be configurable. The process flow shown in FIG. 4A can be executed on the messages received since the last time the process flow was executed, for example. If it is determined that it is time to process received messages, processing continues at step 404, which determines whether or not there are any remaining messages to be processed. If so, processing continues at step 406 to select the next message to be processed.

At step 408, a determination is made whether or not the message includes a financial market instrument reference or references, e.g., ticker symbol(s). By way of one non-limiting example, the message can be parsed to determine whether or not the message contains a reference. If not, processing continues at step 404 to process any remaining messages. If the message includes one or more financial market instrument references, processing continues at step 410 to increment the time span count for each financial market instrument reference contained in the current message, and processing continues at step 412. A determination is made, at step 412, whether the message occurred during the selected time interval, e.g., the last hour. If not, processing continues at step 404 to process any remaining messages. If so, processing continues at step 414 to increment the time interval's count for each reference contained in the current message. Processing continues at step 404 to process any remaining messages.

If it is determined, at step 404, that the all of the messages to be processed in this process flow execution, or run, have been processed, processing continues at step 416 of FIG. 4B. The process flow shown in FIG. 4B can be performed by analyzer 208, for example. The steps of the process flow can include some or all of the steps of the loop shown in FIG. 3, for example. At step 416, a determination is made whether or not any references remain to be processed. If so, processing continues at step 418 to select the next reference. At step 420, a time span average is determined for the selected reference and the current time span, e.g., past week as discussed herein in connection with step 3 a of FIG. 3. At step 422, a percentage change, e.g., percentage increase, is determined, e.g., such as in step 4 a of FIG. 3 discussed herein. Processing continues at step 416 to determine whether any references remain to be processed.

If not, processing continues at step 424 of FIG. 4C. The process steps shown in FIG. 4c can include some or all of steps 6 through 9 of FIG. 3 and be performed by analyzer 208, for example. At step 424, the references are sorted in descending order based on the references' percentage change. At step 426, a number, “n”, of the top references are selected for the current set of references, e.g., a set of trending references. In some cases, the sorted references may not include “n” references, such that the number of the top references selected may be less than “n”. At step 428, a determination is made whether or not “n” references were selected in step 426. If not, processing continues at step 430 to add a number, “m”, of the top references selected from a previous set of references to the current set of references. By way of a non-limiting example, “m” is equal to “n−x”, where “x” is the number of references selected in step 426. Processing continues at step 432 to store the current set of references.

In accordance with one or more embodiments, a textual analyzer can be applied to the messages received by receiver 204 and/or analyzed by analyzer 208. In accordance with one or more such embodiments, the textual analyzer can be used to determine a sentiment of one or more of the received messages. By way of one non-limiting example, the sentiment analyzer can be a component of analyzer 208, and can used to identify a bullish, bearish or neutral sentiment associated with one or more financial market instruments and corresponding references from messages received by receiver 204.

The sentiment analyzer can be trained to predict sentiment, e.g., expressed or implied sentiment, in a message using training data. The training data can include a training set of messages, which are analyzed, e.g., words parsed from the messages associated with sentiment. The training set can include input from human judges identifying a message's sentiment. The trained predictor, or model, can be a probabilistic model, e.g., Bayesian network, which receives input, e.g., words extracted from a message, and provides a sentiment prediction. Based on the predicted sentiment of a message, it is possible to check the correlation of the sentiment with the actual market price of the financial market instrument referenced in the message.

In accordance with one or more embodiments, output of the sentiment analyzer can be used in combination with the percentage change to determine whether a financial market instrument reference is trending up, down, or is neutral. By way of one non-limiting example, for the top “n” selected financial market instrument references determined to be trending upward, each of the references can have an associated percentage increase and “bullish” prediction value. For each reference, the sentiment prediction value can be determined based by the sentiment analyzer using the messages occurring during the time span and containing the reference. The references can be sorted based on each reference's percentage increase and sentiment prediction, with the top “n” references being selected using both the percentage increase and the sentiment prediction for each reference. In accordance with one or more embodiments, the percentage increase and sentiment prediction can be a combined value, e.g., the sentiment prediction can be applied as a weight to the percentage increase. In accordance with one or more such embodiments, and by way of one non-limiting example, the sentiment prediction can have a value on a scale between “1” and “−1”, with a “bullish” sentiment equal to “1”, a neutral sentiment equal to “0” and a “bearish” sentiment equal to “−1”.

In accordance with one or more embodiments, the percentage increase, alone or in combination with the sentiment prediction, can be determined for a market index as a financial market instrument using occurrences in messages of a reference associated with the financial market index and/or references associated with financial market instruments included in the market index. The percentage increase, alone or in combination with the sentiment prediction, can be used to determine a price of the index and/or a trend associated with the market index.

Embodiments of the present disclosure can be applied to different types of messages or data to bubble up the acceleration of the incoming data from data providers 202. By way of one non-limiting example, the functionality described herein can be used to select web hyperlinks, e.g., a hyperlink to a web page containing information and/or content associated with a financial market instrument and/or financial market entity, instead of or in addition to identifying financial market instrument references. By way of a further non-limiting example, received messages can be examined to identifying web hyperlinks contained in the messages, and web hyperlinks that are the most referenced, e.g., as identified using a percentage change value, in the analyzed messages can be identified and presented to users. While the hyperlink can be a link to a web page containing financial market information, it should be apparent that the hyperlink can be a link to other content.

FIG. 5 illustrates some components that can be used in connection with one or more embodiments of the present disclosure. In accordance with one or more embodiments of the present disclosure, one or more computing devices, e.g., one or more servers 210, user devices 212 or other computing device, 502 are configured to comprise functionality described herein. For example, a computing device 502 can be configured as receiver 204, analyzer 208 and/or server 210, which operates as discussed herein in accordance with one or more embodiments of the present disclosure. The same or another computing device 502 can be associated with one or more of data store 508, which can correspond with data store 204, for example. It should be apparent that one or more of the receiver 204, analyzer 208 and/or server 210 can be the same computing device 502, or can be a different computing device 502.

Computing device 502 can serve content, e.g., GUI 102, to user computing devices 504 using a browser application via a network 506. Data store 508, which can correspond to data store 204, can be used to store data from data provider(s) 202, data generated analyzer 208 and/or receiver 204 executing functionality such as that shown in FIG. 3, etc., as well as program code to configure a server 502 to execute the receiver 204, analyzer 208 and/or server 210.

The user computer 504 can be any computing device, including without limitation a personal computer, personal digital assistant (PDA), wireless device, cell phone, internet appliance, media player, home theater system, and media center, or the like. For the purposes of this disclosure a computing device includes a processor and memory for storing and executing program code, data and software, and may be provided with an operating system that allows the execution of software applications in order to manipulate data.
